Which Battery Does My Golf Rangefinder Use? CR2 Finder Table for 22 Models (Bushnell, Blue Tees, Callaway, Precision Pro, Garmin)

Most golf laser rangefinders use one CR2 3-volt lithium battery; the exceptions are rechargeable units (Garmin Approach Z82 and Z30, Blue Tees Series 3 Max+, Bushnell Phantom GPS) that charge over a cable, and a few older long-range Bushnell lasers that take a CR123A. If you need a rangefinder battery and the unit has a screw cap or a small door, it is almost certainly a CR2.

The finder table lists the battery for 22 models from Bushnell, Callaway, Blue Tees, Precision Pro, Garmin and Nikon, using only what support pages and spec sheets state. After it: what a CR2 is, how long one lasts, how to change it, and brand notes including Precision Pro’s replacement program. Bushnell owners get a per-model page at Bushnell rangefinder batteries.

Rangefinder battery finder: which battery does my model use?

Only models with a stated battery type appear. If yours is missing, open the door: a cylinder about 1 inch long is a CR2, a longer and wider one is a CR123A, and a charging port with no door means rechargeable.

What a CR2 rangefinder battery is (and what it is not)

A CR2 is a 3-volt lithium cell about 1 inch long and 0.6 inch across, originally made for film cameras. It is single-use, with a shelf life of around 10 years. Makers use it because lithium holds voltage in the cold and delivers the short bursts a laser needs.

Two things it is not. It is not a CR123A: that cell is about a third longer and slightly wider, also 3 volts, and will not fit a CR2 compartment. And it is not rechargeable: the “RCR2” cells sold as replacements use a different chemistry and voltage, and some rangefinders will not power on with them. Unless your manual lists a rechargeable cell, buy standard CR2 lithium from a name brand.

How long does a golf rangefinder battery last?

A season or more for most golfers, because the laser only fires when you press the button. Bushnell’s Tour V5 support page says the initial battery should last a few months, and a GolfWRX poster playing around 140 rounds a year reckoned $22 of CR2s covered a decade. Rechargeable units are quoted per charge: Golf Galaxy lists the Blue Tees Series 3 Max+ at around 50-plus rounds per 2–3 hour charge.

What shortens it: a winter in a cold trunk, scan mode held down for long stretches, and a button pressed in the bag.

How to change a rangefinder battery

1. Find the compartment. Bushnell Tour units have a screw cap near the eyepiece; Blue Tees, Callaway and Precision Pro use a door. Turn a screw cap counterclockwise; a coin fits the slot.
2. Remove the plastic disc or tab. New units ship with an insulating disc on the battery; Bushnell’s first setup step is to remove it.
3. Check orientation. Follow the diagram inside the cap or door: Bushnell’s Tour V5 guidance puts the positive (+) end outward, and Blue Tees’ Series 4 Ultra steps put the flat negative end inward.
4. Close snug, not hard. Owners on the Titleist forum report stripped threads on a Tour V5 cap.
5. If the display misbehaves, reset. Bushnell’s advice after a swap: hold the power button for 10 seconds.

Low-battery symptoms

A dying CR2 rarely goes from fine to dead in one round. The tells: a dim or flickering display, readings on short targets but nothing at 150-plus yards, two or three presses per reading, and a battery icon in the eyepiece; cold mornings make all of these worse. Swap in a fresh cell before assuming a fault; if it still misbehaves, work through rangefinder not working before you contact warranty support.

Rechargeable rangefinders: USB-C and built-in cells

A growing number of units have no battery door. The Blue Tees Series 3 Max+ uses an internal 3.7V/1,000mAh lithium-ion cell charged over USB-C in 2–3 hours; Blue Tees notes its battery indicator only lights when power is low, so a dark icon is normal. The Garmin Approach Z82 and Z30 and Bushnell’s Phantom GPS handhelds are the same idea. The trade-off: no spare in the bag, so a power bank replaces the two-pack of CR2s, and a worn-out cell is a service job.

Bushnell rangefinder batteries

Every Bushnell Tour laser from the V2 to the V7 Shift, plus the Pro XE, Pro X2 and Pro X3, runs on one CR2; older long-range models such as the Pro X7 use a CR123A, and Phantom GPS handhelds are rechargeable. Bushnell recommends a Panasonic, Duracell or Energizer CR2 and sells an official replacement cap for the Tour V5 and V5 Shift. Per-model details, caps and the 10-second reset are on the Bushnell rangefinder battery page.

Blue Tees rangefinder battery

The Series 2 Pro, the original Series 3 Max and the Series 4 Ultra use a replaceable CR2; the Blue Tees help center walks through the swap: unscrew the door, remove the plastic wrap from the new CR2, flat negative end inward. The Series 3 Max+ and newer models use a built-in rechargeable cell; a USB-C port on the body settles which you own. Lost a battery cover? Blue Tees’ own shop is the first place to look.

Callaway rangefinder battery

The Callaway 300 Pro takes one CR2 behind a battery door; the GGolf two-pack sold for Bushnell, Leupold and Callaway is the retail confirmation. Callaway’s hybrid laser-GPS units charge over a cable. For other Callaway lasers, open the door and match the cell.

Precision Pro rangefinder battery and the replacement program

The NX7, NX9 and NX10 all run on a CR2; R&D Batteries lists the NX10 Slope against a 3-volt CR2. Precision Pro also sells replacement battery doors for the NX9 (post-2022) and NX10 at around $8; a lost door is the most common “battery problem” on these units.

The replacement program: since 2017 Precision Pro offered a Free Battery Replacement Service to registered owners, and the request page is still live. In March 2025 the company posted a notice citing tariff costs, and 2025 threads on r/golf and GolfWRX report the free program ending. Read the current terms before counting on a free cell; a CR2 is around $5 either way.

Gogogo, Eagle Eye, RedTiger and other budget brands

The Amazon-first brands split like Blue Tees: cheaper models take a CR2 behind a door, newer ones are USB rechargeable, and the listing does not always say which, so check the door before ordering cells. Gogogo’s Sport Vpro and the RedTiger units are covered on our model pages; whatever the brand, the CR2 is the same cell.
